UNITED STATES ERICK ERDMAINN, OF IHIMEB'JJ, GERMANY FBIDTIONLESS AUTOMATIC DEVICE FOR RAISING FIR-E WINDINGS ON VERTICAL CONICAL .WINDIN G- UP DRUMS I Application filed October 81, 1927, Serial No. 230,045, and in Germany April 28, 1927.

In wire-galvanizing and tinning-works the inconvenience is experienced upon winding-up the galvanized or tinned wire on the vertical conical winding drums that the 5 wires thereon do not move automatically upwards towards the tapered ends of the drums but form thick bunches at the winding-up point. This inconvenience, which causes entanglin of the wire-windings may be loavoided, or instance by raising rom time to time by means of an iron-rod or other tool the wire-bunch which has been formed to bring the same to a point of the conical drum at which the drum is of smaller diame- 16 ter. The wire-bunch is then fixed at this point by turning it over so that the inner windings are on the outer side and clamp, by their tension, the wire-bunch on the drum. At this intermittent raising by hand and to the turning over, the wires, w ich have run the one on the other in the bunch, are entangled so that it is impossible to subsequently unwind the same in the accurate manner necessary vfor subsequent utilization. The metal-coating of the wires might be damaged when the wires are being raised by hand with the aid of a tool, as the wires in being wound on the drum must rub on the tool.

All these inconveniences are avoided according to the invention, by providing, preferably directly behind the point at which the wire comes into contact with the windingup drum, a disk inclined towards the arrivthe winding-up drum and being rotated by this drum, said disk pushing the wire-windings uniformly upward, owing to its inclined position. n

An embodiment of the invention is illustrated, by way of example, in the accompanying drawings in Fig. 1 in side-elevation, and in y Fig. 2 in top-plan view. A circular disk (2 is loosely mounted at the 1 side of the lower end of the winding-up drum a behindthe pont at which the wire 12 comes into contact with the drum. The disk at is mounted on an axle 0 slightly inclined with regard to the axis of the wire, and is pering wire and pressed permanently against manently pressed, for instance by the action of a spring k, against the drum so that it is rotated at the same circumferential speed as said drum. The disk d exerts, owing to its inclined position, similar to a conveying worm, an upwardly directed push uponthe wire, whereby the wire-windings b are uniformly pushed upward, one winding in touch with the other.

If the disk (Z were stationary and exerted only, this pushing-effect, it would not completely fulfill its object as the wires would rub strongly on the drum so that their coating of zinc or tin would be damaged. It might further happen that the wires are pressed through between the disk and the winding-up drum, essentially for the reason that such drums never rotate. quite steadily and consequentl. move sometimes away from a stationary dis a greater or less great distance.

The desired effect is substantially improved when the edge of disk at is bevelled, the running on of the wire I), which is not strongly stretched, being facilitated thereby and the pushing-efiect in upward direction being also better than when a disk d is used which has a cylindrical edge.

A carriage e is mounted in a slide g at an angle to the drum and carries the axle 0 of ,the disc (2, a spring serving to press this disc against the drum a.

I claim:

1. An automatic device for raising. wire windings, comprising in combination a conical vertical drum, a control element rotatably arranged at the side at the lower end of said drum shortly behind the point at which the wire is coming into contact with said drum, said control element being inclined towards the arriving wire and means for pressing said control element permanently against said drum so that it is rotated from said drum and uniformly pushes the wire windings upward on said drum.

2. An .automatic device for raising wire windings, comprising in combination a conical vertical drum, an axle mounted at the side at the lower end, of said drum shortly behind the point at which the Wire is coming into contact with said drum, said axle being inclined towards the arriving Wire, a. control element loosely mounted on said axle and means for pressing said control element permanently against said drum so that it is rotated from'said drum and uniformly pushes the wire windings inward on said drum.

3. An automatic device for raising wire windings, comprising in combination a conical yertical drum, a carriage at the sidg otf said drum, an axle mounted on said carriage at the side at the lower end of said drum shortly behind the point at which the wire is a coming into contact with said drum, said axle being inclined towards the arriving wire, a control element loosely mounted on said axle and means for pressing said control element permanently against said drum so that it is rotated from said-drum and uniformly pushes the wire windings inward on said drum.

In testimony whereof I aflix in Si ERICH ER ature. NN.
